Welterweight champion Georges St. Pierre tore a tendon in his right abductor during his UFC 100 bout in Las Vegas Saturday night, MRI results confirmed Tuesday.

St. Pierre, who said he snapped his abductor muscle in the third round of his unanimous decision victory over Thiago Alves, had already been handed a medical suspension by the Nevada State Athletic Commission. Heíll be out of action until Jan. 8 unless a doctor says otherwise.

The Montrealer underwent the MRI in his home town on Tuesday to determine the extent of the injury. Even if cleared by an orthopedic doctor, St. Pierre was still under a suspension until Aug. 11 for precautionary reasons, with no contact until Aug. 2.

Three other fighters were suspended for the same length. Yoshihiro Akiyama, who defeated Alan Belcher by split decision, suffered a fractured left orbital bone. If cleared by an ophthalmologist, heíll be able to fight again on Aug. 11; otherwise, heís out until Jan. 8.

Meanwhile undercard winners Jim Miller and Shannon Gugerty have minor injuries that will need doctorís clearance in order for each to fight before January.

Frank Mir and Michael Bisping, both victims of knockouts at the hands of Brock Lesnar and Dan Henderson, respectively, were suspended until Sept. 10 with no contact until Aug. 26.

NOTES: Brock Lesnar and Georges St. Pierre led the nightís paydays, each earning $400,000 for their wins (Lesnarís purse was guaranteed).

what's not to understand? They are based on negotiated contracts ... bisping, brock negotitated better deals ... brock probably said, listen i sell tickets and bisping said, look, i can get you the euro fans ... pretty simple ... the guys near the bottom need to prove themselves so when their contracts end, they can sign new, better ones ... paulo thiago for example was probably happy to get his foot in the door and sign for 8 a fight, then he beat kos and gets a shot at fitch, dana isn't all of a sudden going to say, oh lets re-negotitate your contract to get you something like 20-30 g's a fight .... it's a business and dana is a great business man ...
